FS9 and Win7-64
 

Is this the signal that I will need to install a dual boot nevertheless?

My FS9 installation seemed to have migrated well from my old XP-rig to my new with Win-7pro-64, and it ran in sprint mode with details at max.

Until I started to have some longer flight attempts indeed.

After 20-30 Minutes running and flight time, the simulation all of a sudden goes CTD. No warning, to message, no nothing.

Completely out of the blue. I don'T have any clue. I have an i5 2500, 8 GB RAM and a 1 GB GFXcard.

:cry:

:06:

I'm not sure if this is specifically OS related, but sadly there are too many variables with such a complex install. What I said about it before still holds true for me - a crash every 15-20 hours of play at most, which is more than acceptable for longer flights.

One thing I noticed caused CTDs is when I tried forcing AA/AF settings via the video card options. I accidentally left these on for a bit after playing another game, and had two crashes in a row after about 1hr in flight each. Once I took the settings back to "determined by application", everything went back to smooth and normal.

But again, there are too many variables, both in the system and in your likely FS install... Is there any way you could narrow down possible causes here?

Not that I know off. No error message, no error code, no nothing. Just splash. The same installation worked flawlessly under XP, on my old rig. Even the sequence of sceneries in the scenery registry is the same.

I am totally clueless. It also cannot be that out-of-memory-bug,m since it is not XP now, but W7, which handles more than those 3.5 GB of RAM.

Do you have a file called Uiautomationcore.dll in your root folder? Apparently 64 bit OSs and that file do not get along well. Some people have had success replacing it with this file:

Back up your own of course. Others have simply removed the file and it solved the issue..

Also, are you using anything like the ENB series .dll for lighting effects? It constantly gave me the crashes you refer to.

And if the above is of no use then the best thing to do is look at the event logs under Administrative Tools in Control Panel, it will tell you what the actual error is. I had to do similar hunting when going to Win7 64 on FSX but eventually found and removed all the issues.

Will check those. No ENB lights, AFAIK, and the download site for the first dll gives trouble and rings alarm bells.

Mediafire gives trouble...? Never heard that before..

Both Avira Premium and Windows 7 started to blink red lights. While Avira is know to sometimes call false positives, it is dubious that Windows' settings as I have chosen them also do not like it. I keep some things a bit tighter than the default upper medium settings.

And when a website additonally pops up messages telling me that I need to switch of both AntiVir and Firewall, and also have to switch on all Cookies, this does not raise any more trust on my side. I think it is either bad intention, or incompetent website programmer. Next thing they want is that I have enabled Javascript, eh? :hmmm: :haha:

:arrgh!:

I see what happens when I "delete" that file.

Meaningless anyway, it seems, the dll, and altering it, is with regard to problems with FSX, NOT FS9, I just learned via Google.

Ok, well I have seen people saying they have had issues in FS9 with it as well. I'd grab you a link but it is meaningless to do so.

Anyways, good luck to you.
